Spehro Pefhany k 4 You say pullup resistor, do i have to connect it from pin 14 or? The NAND gates in this chip can only pull the output low, so you need something else to pull the output high assuming that you want to see it go high. I migth be stupid, but I can’t really figure this out. Thanks for you answer, and i do know that the picture is silly, i just dunno how to make schematic. The 74HCT03 has open-drain outputs. So just to be clear, we agree that if both inputs are 1, the output will be 0.

This should mean that the IC is ON. Post as a guest Name. The poor photo of your breadboard is not very helpful. The pullup resistor goes from the NAND gate output pin to the power supply voltage. Joe Hass 7, 1 19 You will need to add a pull-up resistor to see the output go high.
I have connected the pins to datashset resistors to ground, so they can be 0 if no power is on.
This chip just won’t work for me. Home Questions Tags Users Unanswered. Also, please give us a proper schematic. I have recently bought this IC: The funny thing is that whenever I disconnect the wire that goes from pin 7 to ground, the LED starts to light.
It’s a 744hc03 gate.
And a LED to pin 3. This is what the internal circuit looks like on the 74HC03 from the datasheet.
